After the tea garden is stopped, the garden is sealed with 0.3-0.5% stone sulphur mixture, which has good control effect on mites, white mites, mites and leaf diseases.
Sealand is a trustworthy manufacturer of CNG Dispenser Mass Flow Meter, LNG Dispenser Mass Flow Meter, LPG Dispenser Mass Flow Meter, ATEX, CE & IECEx approved.
With its high accuracy, wide rangeability and reliable performance, Sealand meter has been applied in many kinds of industries during the last 8 years. Unlike others who only focus on the measurement of liquid at normal pressure & temperature, Sealand has conquered the difficulty in the measurement under severe conditions, such as high pressure, high viscosity, high & low temperature.
Here are the pictures of Sealand Mass Flow Meter in Dispenser for your reference.

Take CNG (compressed natural gas) for example. As the saying goes, the meter can measure anything else if it can measure CNG. It is quite hard to measure gas under high pressure. The sensor must be able to bear high pressure; in this way, the thickness of flow tube must be increased, so the transmitter shall be more sensitive to detect the signal; however, Sealand made it. Sealand's first model is specially designed for CNG dispenser, and now thousands of this model are put into use on the market.
Tea plantation winter fertilizer management technology
　　 The winter fertilizer management of tea gardens includes fertilization, deep tillage, and garden closure.
    Â
　　 First, fertilization
    Â
　　 In general, the tea plantation is applied to the base fertilizer from the end of October to the beginning of November. The fertilization amount per mu of the mature tea plantation is 1500-3000 kg, or 150-200 kg of cake fertilizer, and 40 kg of compound fertilizer.
    Â
　　 Second, deep ploughing
    Â
　　 Deep ploughing can improve soil water storage and fertilizer retention, eliminate deep root weeds and wintering worms, and create conditions for next year's production increase.
    Â
　　 The deep ploughing time is generally from late October to early November, and the depth of ploughing is 20-30 cm. It should be ploughed once a year.
    Â
　　 Deep tillage should be carried out in conjunction with the application of base fertilizer. When deep tillage, it should also be combined with rhizosphere soil to prevent heat preservation and prevent soil erosion.
    Â
　　 Third, the closure of the park   Â
